METALLIC RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 572,437, dated December 1, 1896.

Application filed December 14, 1895. Serial No. 572,182. (No model.)

To all whom it may concern:

Be it known that I, JOHN S. MITCHELL, of Greensborough, in the county of Caroline and State of Maryland, have invented a new and Improved Metallic Railroad-Tie, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved metallic railroad-tie which is simple and durable in construction and arranged to securelyhold the rails in place and to prevent spreading of the same.

The invention consists of certain parts and details and combinations of the same, as will-be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the improvement as applied. Fig. 2 is a sectional end elevation of the same on the line 2 2 of Fig. 1, and Fig. 3 is an enlarged cross-section of the fastening device for the rail.

Each of the two track-rails A and A is supported on a series of casings B, placed suitable distances apart, each casing being made of metal and formed with an arched or hemispherical top B and a downwardly-extendin g flange B adapted to rest on the ground or the bed of the railroad. Each casing B is provided in its top B with a manhole 0, through which the casing may be filled with earth, sand, or other loose material, so as to pack the casing until it is at the desired height.

In the top or center of the casing B is formed a longitudinally-extendin g recess B adapted to receive a strip D, of hard rubber or similar material, on which rests the base of the rail A or A, as is plainly indicated in Figs. 2 and 3. At the sides of the recess B are formed longitudinally-extending seats B in which are seated L-shaped plates E and E, engaging the top of the base of the rail, as well as the inner and outer sides of the rail, as is plainly indicated in the drawings.

The plates E and E are securely fastened in place on the top B of the casing by suitable bolts F, as shown, but other means may be employed. The ends of the plates E and E abut against the longitu(finally-extending shoulders 13 formed on the sides of the seats B and integral with the top B.

Now it will be seen that by the arrangement described the rail is seated on the top of the casing and is securely held in place thereon by the clamping-plates E and E, bolted or.

in place. By this arrangement two opp0- sitely-arranged casings, as well as the corresponding inner clamping-plates E, are consequently spreading of the casings and the rails held thereon is entirely prevented.

The casing A may be round, as shown in full lines in Fig. 1, or square, as indicated in dotted lines in said figure, but it is evident that other suitable forms may be selected if desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A metallic railway-tie, comprising two casings having at their upper parts clampingplates which engage the opposite sides of the rails, and binding-rods extending between said casings, each rod being secured at one end to one of the clamping-plates on one casing and extending diagonally downward and connected at its opposite end with the lower portion of the other casing, substantially as set forth.

2. A metallic railway-tie, comprising two casings adapted to support respective rails, clamping -plates on the respective casings which engage the sides of the rails thereon, rods extending between the casings, each rod being connected at one end to one of the clamping-plates of one casing and extending diagonally downward and having its opposite end connected to the lower part of the lower casing, said rods being crossed over each other, and a clamping device for securing the rods together at their crossing-point, substantially as set forth.
